hi santosh,

just curious why the proposed solution is constrained to only use LDP ?

IMO what you have suggested here would just fit nicely for protecting
segment-routing node labels as well. segment routing node-labels are
"calculated" in a similar fashion than LDP labels as such my guess would
be that this solution applies to SR node labels as well.

suggest to generalize it to:
"Fast Reroute for Node Protection in hop-by-hop based LSPs"

thanks,

/hannes
